    Two distinct authentication surfaces, and they belong to different systems. The CMS content
    API authenticates with a Directus static token or session bearer token; the client platform
    authenticates humans through CarbonFarm's Auth0 tenant. Neither is documented publicly —
    everything below was read off machine-readable endpoints the company serves anonymously.

    Directus static access token passed as a query parameter. Directus' own guidance is to prefer
    the header form; a token in a query string lands in access logs and Referer headers.

  note: >-
    Organization-scoped login: app.carbonfarm.tech redirects with
    `organization=org_PyIwqJe0CACfELBB&organization_name=carbonfarm`, so access is bound to an
    Auth0 organization — a tenant must exist before a login can succeed. The scope set is Auth0's
    default OIDC claim set, not an API permission model; no resource-server scopes are advertised,
    and /.well-known/oauth-protected-resource returns 404. That is why no `scopes/` artifact was
    written — there is no API scope surface to record, only OIDC identity claims.

  CarbonFarm publishes no authentication documentation. There is no developer portal, no API
  reference, and no getting-started page anywhere on carbonfarm.tech — the site's only
  developer-adjacent link is "Client Login".
